Correct Answer - Option 2 : Spinal Cord
Reflex action is an automatic response to nerve stimulation that results in the activity of some organ without the intervention of will.
-
A reflex is an involuntary and nearly instantaneous movement in response to a stimulus.
- The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc.
-
Reflex action takes place without thought, i.e., it gives a reaction to stimuli. It is an involuntary action. It is controlled by the spinal cord.
- The spinal cord acts as a link between spinal nerves and the brain. If the reflex action is controlled by the spinal cord it is called spinal reflex action and if it is controlled by the brain it.is known as a cerebral reflex action.
Thus, it is concluded that reflexes are usually controlled by the Spinal cord.
- The hypothalamus is located below the thalamus in the brain and is part of the limbic system. The hormones from the hypothalamus govern physiological functions such as temperature regulation, thirst, hunger, sleep, mood, and the release of other hormones within the body.
- The frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem-solving, social interaction, and motor function.
- The Medulla oblongata or simply medulla is a long stem-like structure that makes up part of the brain. It is anterior and partially inferior to the cerebellum.
